ParentPage. aspx:
Window. showModalDialog ("DialogPage. aspx? Para1 = aaa & para2 = bbb ");

DialogPage. aspx:
String str1 = Request. QueryString ["para1"]. toString ();
String str2 = Request. QueryString ["para2"]. toString ();

You can pass the related values of the selected row of the DataGrid in the mode dialog box.
